Amkor Doubles Down on Arizona: $12B Advanced Packaging Campus Expansion
AMKR has more than doubled off its 52-week low of $24.6.
Summary
Amkor is expanding its Arizona advanced packaging and test campus with a Phase 2 that adds 60,000 square meters of cleanroom space, bringing the total to approximately 93,000 square meters. The planned investment jumps to about $12 billion, up from the Phase 1 commitment, driven by customer demand that has already exceeded Phase 1 capacity. Construction is slated to begin late 2027 with completion by end of 2029, and the combined campus is expected to support over 3,500 Arizona employees. This follows the June TSMC partnership and July NVIDIA collaboration, reinforcing Amkor's position as the first U.S. OSAT for high-volume advanced packaging. The scale of the investment—roughly equal to the company's entire market cap—signals a major bet on domestic semiconductor manufacturing and long-term customer commitments. Watch for further details on customer prepayments or government incentives that may offset the capital outlay.
